Scan for duplicates by dragging files & folders on its window or its Dock icon, or choose files from the open panel. Organize frequently scanned files & folders in a Quick Scan and launch it with a keystroke.

Featuring a new file scanner engine, Singular shows real scan progress and can be stopped at any time.

Singular keeps by default a copy for each file so you can safely trash duplicates. If you change your mind, Singular keeps a log of what and when something has been moved to the Trash with its original location.

I run a Mac Underground file server and I have it running on a dedicated iMac G-5 with a 250 GB HD. It is nearly full. Files are being uploaded & downloaded 24/7/365 so scanning for duplicates is something that I have been doing daily since 1992..

The best is the duplicates module in FileBuddy9, but for normal peeps I strongly suggest using TidyUp!

If I may suggest: check filesize first, and don't even bother checking filenames. I have many things that are named identically that are nothing alike (and that's without including the rather large amount of source code on my system). That alone should speed it up dramatically, especially on larger scans.

I'm adding other comparison criteria: SHA-1, file name, size in bytes. Maybe there's a smarter way to avoid calculating the hash regardlessly, but it requires a two pass algorithm. Anyway, I'm open to suggestions and criticism :)
